VACUUM-INSULATED BOTTLE.

Specification of Letters Patent.

Patented May 18, .lQO'Q.

To all whom it may concern:

Be it known that I, GARRY P. VAN Wyn, a citizen of the United States, residing at New York, in the county and State of New York, have inventeda new .and useful Vacuum- Insulated Bottle, of which the following is a specification.

This invention relates to vacuum insulated, or double walled vessels with a vacuum between them; and has for its object to provide a vessel of this kind in which the asbestos supports between the walls shall be so 10- cated as to both brace and support the inner wall; a further object being to so locate, and form these supports that they will be forced into the bracing and su portin position during the formation of t e bott e.

The invention is illustrated in the accompanying drawing in which,

Fi re 1, is a central vertical section of a doub e walled vessel constructed according to my invention; Fig. 2, is a sectional view I thereof on theline 22 of Fig. 1.

' Heat is then applied'to the lower In the drawin 4, indicates the inner wall of my improved ottle, and 5, the outer wall. The supports between the walls referably three in number, are indicated y 6. In Fig. 1 I have indicated the method of placing these supports in position.

In the manufacture of these bottles, the outer wall, or envelop, and the inner wall, or receptacle, are formed in molds, the outer part being much longer than the receptacle. After annealing, the bottom of the outer part is cutoff so that the receptacle can be placed inside after which the two parts are fused together at the lip 7. The supports 6, are then placed in position, as indicated in dotted linesin Fig. 1, the supports being of sufficient length to allow the lower end to project beyond the base of the inner wall. part of the outer wall, the position of which is indicated in dotted lines, and this part is melted in beneath the inner wall, as shown in full lines, during which operation the lower ends of the supports are forced into very close contact with the rounded corner 8, of the inner wall, and the contraction of the outer wall when cooling will serve to draw the base of this part a trifle nearer the -base of the inner Wall thereby compressingthe asbestos supports between the walls.

By having a portion of the supports between the side walls, and a portion between the base walls, the inner wall is both braced against lateral vibration and supported against vertical strain, as will be readily understood; and by placing these sup its the w s are cold so far as the upper parts'of the supports are concerned, and then have the advanta e of shaping the lower parts "to the base wa s by the glass of the outer wall in a semi-melted condition, and-the contraction of this heated glass upon the supports thereby insuring a very effective bracing. By this construction I can get a little firmer bracing of the parts owing to the fact that I can force the su ports tightly between the side walls, and the turning in of the outer wall not only forces in the lower end of the supports but compresses the ends at the same time.

While I have described the supports as becondition, it is evident that the lower ends of the su ports could be turned in and fastened to the ase of the inner wall by cement, or in any desired manner before the outer wall is closed in or that stri s of asbestos, or other resilient material, cou d be cut the required shape to fit against the base of the inner Wall when. the ends were shoved up between the side walls. This would not alter the purpose of my invention which is to provide a pluralthickness whereby the vacuum walls will be spaced a uniform distance apart, said strips bein so proportioned in size, and somounted t at one end of each strip will project above the curved ortion between the bases and sides of the wa ls to engage the side walls positively, while the other end of each strip will project below said curved portion to enga e the base walls ositively, and. the centra portions of said strips are wedged between the said curved portions of said walls, whereby the inner wall 1s both supported and braced, and the breakage of the integral connectionbetween the walls at the lip is substantially prevented.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. A vacuum insulated bottle com rising double Walled glass vessel integra ly conresilient material mounted between the Walls,

in this particular position, I have the a van tage of lacing the supports in position when ity of strips of resilient material uniform in.

ing carried in by the glass in a semi-melted nected at the lip, and a plurality of strips 'of one end of each of said stri s engaging the side walls, and the other en s thereof engaging the base walls, for the purpose set fort 2. A vacuum insulated bottle comprising a 5 double walled glass vessel with a curved portion between the base and side walls, said walls being integrally connected at the li and a plurality o 15 tegrall connected at the hp, and a plurality .of resi -ent and flexible supports mounted between said walls, said suptports bein in engagement with the sides 0 both wa s, and

strips of resilient materia mount-. ed between said walls; and'en aging said being held in contact with the base of the nner wall solely by the outer wall, as and for 20 L the purpose set forth.

4.- A vacuum insulated bottle comprising a double walled vessel inte rally connected at the hp, and a pluralit 0 supports mounted withln the vacuum 0 amber, and enga 'ing 25 both the sidewalls and base walls thereo adjacent to the connecting portion between said side and base walls.

In testimony whereof I have signed my name to this specification in the presence of 3 two subscribing witnesses.
